A listener is at rest with respect to the source of sound. A wind starts blowing along the line joining the source and the observer which of the following quantities don't change ?

A

Time period

B

Velocity of sound

C

Frequency

D

Wavelength

Text Solution

Verified by Experts

The correct Answer is:
A, C
When `V_(L)=V_(S)=0`, there is no change in apparent frequency and hence time period.

Two point sources of sound are kept at a separation of 10 cm. They vibrate in phase to produce waves of wavelength 5.0 cm. What would be the phase difference between the two waves arriving at a point 20 cm from one source (a) on the line joining the sources and (b) on the perpendicular bisector of the line joining the sources ?

What physical change occurs when source of sound waves is at rest and the listener moves?

Is there a Doppler's Effect for sound when the observer or the source move at right angles to the line joining them?

The apparent change in frequency of a sounding source and observer in relative motion is

Distance between the sources is one meter. An observer observes minimum intensity at some point outside the line joining the sources, then the wavelength of the wave should be –
